CENTRIFUGAL PUMP Russian patent published in 2007 - IPC F04D13/12 F04C11/00 

FIELD: gas turbine engineering.

SUBSTANCE: centrifugal pump comprises housing provided with inlet and outlet branch pipes, bearing thrusts mounted in the bore made in the housing, radial centrifugal impellers provided with individual passages for supplying fluid and mounted in the driving and driven pinions provided with ring bores at the bases of the teeth that engage the baffles between the sucking space and pressure space set in the bearing thrusts. The bearing thrusts are made of two sliding bearings common for the driving and driven pinions. One of the bearings has side slot that connects the individual passages for supplying fluid to the radial centrifugal impellers with the inlet branch pipe. The depth of the slot is determined by the plane passing through the centers of the bearings.

EFFECT: enhanced efficiency.
